To put it in perspective, it's one thing for a company to offer a sale on a product or service at a certain prize for a limited time. Most customers of cable companies, for example, will jump on a discounted price for cable services for 2-years with the understanding that their rate will increase after that 24-month period. But then when you get your bill after that 2-year period not only do you notice the cost increase - which again, you agreed to when you accepted the service - but you also suddenly find all these "additional charges" in some cases listed as "Misc. Service Fee" of some sort for things you had no idea you'd be subjected to when you agreed to the contract. In other words, your limited time offer for 2-years of service at $29.95/mo suddenly balloons to $59.95/mo and you're left wondering, "Where the hell did those charges come from," and you never really get a straight answer from the service provider. Then the next thing you know your bank account is hit...your credit/debit card is heavily charged and you find yourself deep in debt and for what? Some company sought to dominate market share?
I hear of or read about these types of stories all the time. It gives certain businesses/industries a bad name. Still, for those who say it's the customer's fault that the failed to read and understand their service contract, I say I hope you have a magnifying glass and an attorney next to you as you read. The details are literally in the fine print, but who can honestly read that stuff? This was, in part, what financial reform was about - protecting the everyday consumer from such immoral business practises. So, if all facets of the telecommunications industry are doing these things now, what makes you think a company that once had a terrible reputation of doing this - in fact, I'd say AT&T pioneered the practise - what makes you think they'll do right by their customers once they absorb T-Mobile into their clutches?
It's like another poster said, Verizon does provide a good quality service (although I do think their prize is rather high). But if this AT&T/T-Mobile merger is allow to go through they'll get drowned out and the only way the cell phone industry will be able to compete is if the fed breaks them up just as it did Bell Telephone years ago and force them to become smaller divisions of itself.
